M Series II Monochromators
Ultimate Resolution Monochromators (1 and 1.25 Meters)
The M Series II monochromators are the large focal length monochromators of choice for the most demanding spectroscopy applications. Ideal for extremely high resolution requirements such as Raman spectroscopy and emission structure analysis, and essential for the most demanding stray light rejection, the M Series also features optional dual automated entrance and exit ports for to extend the versatility of these outstanding spectrometers. These monochromators also benefit from the highest quality of gratings, also designed and manufactured by HORIBA.

Overview
Single entrance and one or two exits
The M Series II is a group of high performance, research spectrometers with long focal length. The 1000M features a 1000 mm focal length with f/8 aperture. The 1250M has a 1250 mm focal length. Designed for experiments that require extremely low light-levels, the M Series II delivers unmatched spectral resolution for a variety of research applications, including:
- Raman
- Plasma emission
- Photoluminescence
- LIBS (Laser-induced breakdown spectroscopy)
- LIPS (Laser-induced plasma spectroscopy)
- LIF (Laser-induced fluorescence spectroscopy)
M Series II spectrometers feature a 150 nm to 15 μm wavelength-range (depending on the grating and detector used). A fine step-size of 0.00025 nm allows full resolution to be obtained while delivering superb accuracy (± 0.05 nm) and repeatability (± 0.005 nm). Other features include high-precision micrometer slits, a high-precision stepper drive, and a USB 2.0 computer interface.
Dual entrance and exit ports, with selectable swing mirrors, enhance the versatility and flexibility of the M Series II. This dual exit-port option allows for simultaneous mounting of two detectors. Data-acquisition can also be automated from two different optical setups by toggling between entrance ports. The M Series II is compatible with HORIBA Scientific’s complete library of interchangeable gratings, and full line of single-channel detectors, PMTs, and accessories.
Hardware
Monochromator Hardware
The M Series II uses a precision worm/wheel gear drive mechanism under stepper motor control which enables a user to drive precisely to a given wavelength or scan over a wavelength range. The drive has a scan range of 0 Å to 15 000 Å (0–1500 nm) for a 1200 gr/mm grating. The wavelength resolution of the drive is user-selectable with a minimum step size of 0.000 25 nm (with a 1200 gr/mm grating). The drive must be initialized upon powering up. The initialization process precisely homes the drive mechanism, allowing for very accurate and repeatable wavelength settings. The drive will hold position indefinitely as long as the unit is on. If the system is powered down, there can be a small shift in drive position.
Slits
The M Series II micrometer slit provides a continuously adjustable slit-width from 0 mm to 3 mm. The micrometer scale provides an accurate, repeatable means for setting the slit-width. The scale reading is in millimeters with the fine lines representing 2 μm increments. Although the slit-width can be set to 0, we recommend that the slit-width be set to a minimum of 6 μm for the 1000M and 3 μm for the 1250M.
You can add accessories to the M series spectrometers to obtain optimum results for a variety of applications. Most accessories can be mounted directly to the slit assembly or to the slit assembly via an adapter.
Gratings
World Class Diffraction Gratings Manufactured by HORIBA
A Proud Tradition of Excellence
Since the acquisition by HORIBA of Jobin Yvon, a spectroscopy company founded in 1819, HORIBA Scientific has continued to define the leading edge of the Optics of Spectroscopy.
For the last 40 years HORIBA Scientific has taken a leading position in the design, development and manufacture of master and replica diffraction gratings. HORIBA Scientific diffraction gratings are found in both high volume OEM instruments and in world class cutting edge scientific applications. Our pattern of leadership in optics has been hallmarked by the continuing development of both classically ruled and holographic diffraction grating technologies. This led to the introduction in 1967 of the aberration corrected holographic grating and subsequently ion etched and blazed concave and plane holographic gratings.
The M series of spectrometers take full advantage of the highest quality of gratings that HORIBA designs and manufactures.
A Vast Array of Choices
There is a wide selection of gratings to choose from depending on optical requirements. Gratings are 50 x 50 mm for the M Series. There are three different types of gratings available; classically ruled, holographic, and blazed holographic. There is also a flat mirror that may be ordered for the dual grating turret option.
Ruled gratings | Select for applications where high throughput or low groove density is required, or when working in the infrared. Typically, they have high throughput at the cost of higher stray light. |
|---|---|
Holographic gratings | Available in higher groove densities for finer resolution requirements and are excellent choices for experiments with laser excitation such as Raman or laser induced photoluminescence. They provide the lowest possible stray light possible, sometimes at the cost of lower throughput. |
Blazed holographic gratings | These gratings have the same advantages as holographic gratings with better throughput. |
Groove Density
Ruled gratings and blazed holographic gratings have two fundamental parameters to choose from; the groove density, expressed in grooves (or lines) per millimeter, and the blaze angle which nominally refers to the peak reflectance wavelength expressed in nanometers.
The groove density of the selected grating affects the resolution and mechanical scanning range of the monochromator. Below is a reference chart showing the affect groove density has on the mechanical scanning range of the monochromator as well as the reciprocal linear dispersion of the slits.
